Re: [Interest] QQuickGrabItemResult on iOS
Hi Michael, Voted. Thank for suggestion! Change the code to use canvas is a reasonable method . Just the work load is huge.. I have an arrow component in QML and linked with a lots of images in different size with text arranged in grid. So before go into the canvas approach, I would like to try few more thing first. Before Qt 5.4 is out , I have written my own version of grabToImage(). And I just found that the code works in iPhone with Qt 5.3.2 . However, it use QQuickShaderEffectTexture and the class is no longer available in Qt 5.4. I would like to take a look and see can it be fixed by using private API.

QQuickItem::grabToImage() not working on iOS for me either in 5.4.0 and 5.4.1. Here’s a bug report, please up-vote if it’s important to you: https://bugreports.qt.io/browse/QTBUG-44450. Regarding work-around: perhaps get a 2D context in a Canvas object and paint the object in onPaint()? This is something I’ve been meaning to try.

[Interest] QQuickGrabItemResult on iOS
Has anyone had any success using QQuickItem::grabToImage on iOS? I'm using it successfully on OSX and android, and it works perfectly fine in the iOS simulator (iOS 7 and 8), but when I run on an iOS device, the images come up empty. I've tried on both an iPad 2 and an iPhone 5s (both running iOS 8), but I don't have access to any devices with iOS 7. Any advice on how to root-cause this?
